It is a known fact that men tend to have wider shoulders than women. But I have a few question. I have so many it would be nice to hear the development of human shoulders in human being from somebody who knows a thing or two about biology.

Practically, I'm a male and I think my shoulders are wide and should really not be that way. I read somewhere that testosterone broadens shoulders over age but I'm only 18 and from a quick look at my own body I can tell my testosterone levels are not as high as they should be; I have guitar shape: I can close an entire corset on my waist and breath. I heard somewhere that males who tend to have guitar body shapes have low testosterone, so how come my shoulders are so wide? Did all the testosterone go to the shoulders or something?

I read a lot about shoulders because it really upsets me, and I came across a lot of people saying it is just a bone structure and males seem to have board shoulder for muscle mass. I do admit I was taking swimming lessons for 2 years when I was 11-12 or something, but at that time I was anorexic-slim and somebody told me my shoulders couldn't have broadened due to lack of calcium and bad eating habits. Since then I haven't done any physical exercise whatsoever.

To be honest, I'm just trying to convince myself there is nothing I could or should have done concerning my wide shoulders and it's my natural bone structure.

When I was swimming my dad told me it's good for the spine because the muscles are getting stiffer and balance the spine. Could that happen to the shoulders as well? Can muscles broaden shoulders? If my muscle mass decreases around the shoulder area will the shoulders adjust back to their original form?

All I know is that Hormone Replacement Therapy of estrogen reduces the fat and muscle mass around the shoulders thus making them slimmer.

You're not going to change your internal structure much, and you can't apply generalities of development and shape too closely to an individual. You're shaped like you're shaped, and a look at it won't tell you much about hormone levels.

I'm totally agree with you.Certain two facts on this post unequivocally the best we have all had.You can't apply generalities of development and shape too closely to an individual.I agreed what's said above!!!
